Storybook v5 to v6

Storybook component converter from v5 to v6. This script converts Storybook component written by stories function to CSF (Component Story Format).

Since this program is specific to BBQ (UI Library for BASE.inc), you have to custom some part of "index.ts" or "modules.ts" in more general use.

The command below generates "example/v6.js" using "example/v5.js".

$ yarn run convert ./example/v5.js ./example/v6.js
